ABSTRACT
Objective To explore the health inspector effect on the score of hygienic degree of hostels. Methods Using the scale for hygienic degree of hostels, 38 health inspectors from 9 sections in the Bureau for Health Inspection and Supervision of Haidian District in Beijing, scored 621 hostels in the district. The multilevel statistics model has been used to analyze the health inspector effect, of which the index is intra-class correlation (ICC), in the double level model structured by hostels as the level 1 unit and inspectors as the level 2 unit, and in the triple level model structured by hostels as the level 1 unit, inspectors as the level 2 unit and the sections as the level 3 unit. Results In the double level model, ICC of the level 2 unit is 0.142 8. In the triple level model, ICC of the level 2 unit is 0.0000 and ICC of the level 3 unit is 0.154 1. Conclusion There is inspector effect influencing the score of hygienic degree. And the effect seems to be more similar in one section comparing with the other ones.
